This may not be the only example of a cluster bomb used recently, as this video also catches the remains of a bomb that looks like it could possibly be a larger RBK series cluster bomb

Update August 29th This video has been posted online that appears to show a child that has been given an unexploded cluster muntion from the above bomb so he can be filmed with it. Needless to say this is incredibly dangerous and irresponsible

Update August 31st HamaEcho has spotted another video of an RBK-250 cluster bomb carrying PTAB-2.5m cluster bomblets (according to the writing on the casing) dropped in the Dier Ez Zor region
